Printed Circuit Board (PCB) Inspection

Machine Vision Consulting developed a vision system to improve PCB yield and reliability through detection of defects in multi-layer printed circuitry on ceramic substrates. The machine vision system inspects and identifies defects on printed circuit boards (PCBs). PCB defects detected include: contraction, chipout, smear, and contamination.
